Test Broadcom BCM94360NG 802.11ac WiFi Card
I have a Broadcom BCM94360NG 802.11ac WiFi Card which I'd like to see if I can get running on the Pi.
Haven't tried any Broadcom wireless gear yet, so hopefully it's not too difficult.

Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma
It seems like this card is very popular in the Hackintosh community, as it works on Hackintosh builds with no additional drivers or patches needed.
Information on getting it going on Linux is a little more sparse. The brcm80211 driver in the kernel doesn't mention anything about this chip.
That driver does mention:
Framework for supporting new chips, including mac80211-aware embedded chips.
Ah but the chip itself is BCM4360, and it looks like that may be supported in that driver. The Arch Wiki states that 5GHz might not work on higher channels with this chip and that driver, though.
Device Drivers
> Network device support
> Wireless LAN
> Broadcom 43xx wireless support (mac80211 stack)
Seems like it was enabled in the default config, at least in the 5.10.y kernel.
I rebooted; first reboot, got a kernel panic, but 2nd reboot it was clean.
$ lsmod | grep mac
mac80211 905216 1 b43
libarc4 16384 1 mac80211
brcmfmac 323584 0
brcmutil 24576 1 brcmfmac
cfg80211 860160 3 b43,brcmfmac,mac80211
But I'm not seeing the interface when running iw dev—only the built-in interface.
Interesting... apparently you have to install a separate driver from the non-free repo (which is enabled by default on Pi OS in /etc/apt/sources.list):
sudo apt-get install broadcom-sta-*
sudo modprobe wl
echo "wl" | sudo tee -a /etc/modules
Seen here: https://unix.stackexchange.com/a/175843/16194
Problem, though—I'm booting from my compiled 5.10.16 kernel, the installable raspberrypi-kernel-headers are built for the current kernel installed via apt, 5.10.11. So the driver compilation that happens during apt install fails:
Setting up dkms (2.6.1-4) ...
Setting up broadcom-sta-dkms (6.30.223.271-10) ...
Loading new broadcom-sta-6.30.223.271 DKMS files...
It is likely that 5.10.16-v8+ belongs to a chroot's host
Building for 5.10.11-v8+, 5.10.16-v8+, 5.4.51+, 5.4.51-v7+, 5.4.51-v7l+ and 5.4.51-v8+
Building initial module for 5.10.11-v8+
Error! Bad return status for module build on kernel: 5.10.11-v8+ (aarch64)
Consult /var/lib/dkms/broadcom-sta/6.30.223.271/build/make.log for more information.
dpkg: error processing package broadcom-sta-dkms (--configure):

Ah... in the kernel, I may be able to use BRCMSMAC, which is used for PCIe, and was disabled by default. From the driver wiki (https://wireless.wiki.kernel.org/en/users/Drivers/brcm80211):
Location: → Device Drivers
→ Network device support
* → Wireless LAN
* * → < > Broadcom IEEE802.11n PCIe SoftMAC WLAN driver
* * → < > Broadcom IEEE802.11n embedded FullMAC WLAN driver
* * * → [ ] SDIO bus interface support for FullMAC driver
* * * → [ ] USB bus interface support for FullMAC driver
* * * → [ ] PCIE bus interface support for FullMAC driver
For the PCIe SoftMAC WLAN driver (brcmsmac) you need to enable select the BCMA bus driver as well:
Location: → Device Drivers
* * → Broadcom specific AMBA
* * * → <M> BCMA support
* * * * → [*] Support for BCMA on PCI-host bus
* ```
But it's not showing up as a loaded module after installing it and rebooting:
$ lsmod | grep mac
brcmfmac 364544 0
brcmutil 24576 1 brcmfmac
cfg80211 860160 1 brcmfmac
$ ls /lib/modules/5.10.16-v8+/kernel/drivers/net/wireless/broadcom/brcm80211/brcmsmac/
brcmsmac.ko
Looks like it's blacklisted by default because I installed those other packages earlier... oops:
$ cat /etc/modprobe.d/broadcom-sta-common.conf
# wl module from Broadcom conflicts with ssb
# We must blacklist the following modules:
blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
install wl /sbin/modprobe --ignore-install wl $CMDLINE_OPTS
$ cat /etc/modprobe.d/broadcom-sta-dkms.conf
# wl module from Broadcom conflicts with the following modules:
blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
So tried a modprobe and got:
$ sudo modprobe brcmsmac
$ dmesg
